Abstract

The invention provides a flow guiding device of a wind generating set and a control method thereof as well as the wind generating set. The flow guiding device comprises a wind guiding screen and staycables, the first ends of the stay cables are fixed to a tower of the wind generating set, the second ends of the stay cables are fixed to the ground, and the wind guiding screen is arranged between every two adjacent stay cables to form a flow guide surface inclined relative to the vertical direction. According to the flow guiding device of the wind generating set and the control method thereof as well as the wind generating set, the flow field around the wind generating set can be changed, the actual wind speed flowing through an impeller is increased, and the generating capacity is increased.

Description

technical field [0001] The invention relates to a flow guide device of a wind power generator set, a control method for the flow guide device of the wind power generator set and a wind power generator set including the flow guide device. Background technique [0002] In large-scale wind turbines, in order to save the tower material of the wind turbine and reduce the tower manufacturing cost and transportation cost, a narrower tower can be used, and a stay cable structure can be set on the tower, for example, as figure 1 As shown, the tower is fixed to the ground by three multi-strand steel wire ropes at a certain angle with the vertical direction, thereby reducing the moment and load between the bottom of the tower and the ground, and improving the stability of the tower. [0003] However, in the wind power generating set with this structure, due to the limitation of the wire ropes, the swept area of ​​the blades may be small, which affects the power generation of the wind p...
